Satellites and Satellite TV
Satellites: What Are They?
When most people hear the word ‘satellite’ they probably picture a man-made machine floating around in outer space beaming telephone calls and satellite TV back down to the planet. Although this would be an example of a satellite, it’s not the only kind. In fact, a satellite is technically defined as anything that is caught in orbit around something else. For example, Earth can be considered a satellite of the Sun, while the moon may be considered a satellite of the Earth since they are both in another object’s orbit.
The satellites we usually envision are the ones we use to relay information. These are usually called artificial or man-made satellites. These satellites are used for everything from providing GPS driving directions to broadcasting satellite TV. In fact, without the satellites we have today, everything from our telephone service to our ability to monitor weather would be drastically affected.
Satellites: Why Do We Need Them?
In the simplest sense, satellites are a relay point for information; which basically means that they receive information from one source, and transmit that information to another source. In order to send transmissions from one point to another, however, there needs to be an unobstructed straight line between the two points. In other words, there needs to be a clear line of sight.
Since the earth is spherical, transmissions made from one ground level location to another ground level location are inherently limited since the curvature of the earth itself will prevent a clear line of sight after only a short distance. For this reason, ground level transmissions are usually sent from towers in order to create a longer line of sight. Satellites are simply an extension of this idea.
A satellite that is orbiting earth has a clear line of sight to a profoundly larger area, and thus can effectively transmit a signal across greater distances. In fact, one satellite alone can potentially transmit to the entire United States when properly positioned.
Satellite TV
One of the most notable uses for satellite has been in the telecommunications area. Satellite TV, for instance, is a great example of how satellites can not only increase efficiency, but quality as well.
Since satellite TV can transmit a signal across such a large area, just one satellite alone can bring satellite TV to millions of people. Rather than run cables to each and every home like the cable companies do, satellites can simply transmit the information across the sky and into our homes.
Additionally, Satellite TV transmits digitally which allows the signal to go significantly further while carrying much more information. The satellite TV transmissions are so effective that satellite TV companies can tout a 99.9% signal reliability. The large amount of information that can be sent over a digital transmission allows for satellite TV companies to broadcast hundreds of channels as well as tons of high definition programming all over the country.
The effective use of satellites allows for satellite TV service to be available everywhere in the United States including Hawaii, Alaska and Puerto Rico. Because satellite TV companies don’t face the high costs of running cable to each and every home, and then continually maintaining that cable, the satellite TV companies can provide service to residents in rural or remote locations.
